Specification of Letters Patent.

Patented. Feb. '25,, 1908.

Application filed April 6 D07. Serial No. 366.799.

To; all whom it may concern:

Beit known that 1, Emma R. WILLIAMS, a citizen of the United States,residing; at Downer'sGrove, in the county of Dupage andStato-of-lllinois, have-invented new and useful. Improvements inPrinting Frames, of which the following is a specification.

This invention relates to a photographic printing frame of that typehaving pockets or casings at opposite sides for receiving;- the mom forthe negative film, whereby the can be wound on one spool while unwindingfrom the other and thus passed across the printing frame to permit ofthe printing of the negatives in a successive order and with greatfacility.

The invention has for one of its objects to improve and simplifytheconstruction and operationof devices of this character so as to becomparatively easy andinexpensive to Y manufacture, convenient tomanipulate, and

efficient andreliable in use. 1

A further object of the-invention is the provision of a printin framehaving 'hin edly connected sections etween; which the fi m is passedfrom one casing to the other, the casings being located at opposite endsof the frameand provided with doors for facilitating the removal andinsertion of the filmy carrying spools p With these objects in view andothers, as willappear as the description proceeds, the inventioncomprises the nove features of construction and. arrangement of partswhich.

will. be more fully described hereinafter and set forth withparticularity in the claims appended hereto.

Intheaccompanying drawings, which illustrate one of the embodiments ofthe inven-.

tion, Figure 1 is a perspectiveview of the printing device-with itsparts in closed posi-- tion.- Fig. 2 is a. horizontal-section on line2-2, Fig. 1. Fig. 31is apers ctive. view of. the device showing thehinge section of the -frame open. Fig. 4 is a vertical section on framethat is hingedly connected at its lower end with the mam frame to fitbetween the top and bottom members of the latter. These frames orsections of the device are preferably constructed of wood and are eachprovided with central rectangular openings 2 and 3 for receivingrespectively, the glass plate 4 and back 5 which latter is composed oftwo parts connected by a hinge 6, as shown in Fig. 1, and each partbeing-provided with a leaf spring 7 whose extremities engage underprojections S or plates on the frame section B in the usual manner.section Bis held in closed position by asuit-v able fastening such as apin 9, extending through the top member 1 of the section A and entering;an opening 10 in the top of the section B, and when in closed position,the latter section is held spaced apart from the main section A, asclearly shown in Fig. .2 for accommodating between the sections the film11,

The topand bottom members. 1 of the section A have circular enlargements12 at their extremities to form the heads of the cylin- -drical casingsor pockets 13 extending vertically at the opposite ends of the printingframe-J These casin s orpockets are referably constructed of seetmetaland eac has a door 14 hinged at 15- for permitting the doors to swingbackwardly, and when the doors are closed, as shown in Figs. 1 and 2,their free edges overlap and bear against the back of the section B andare locked in place by the tumable fastenings 16. On the inner sur- Theface of each lower head or enlargement 12, as

shown in Figs. 3 and 4, is a boss 17 formingnal bearing for the lowerend of one; of the fi spools 18, the boss 17 having a. pivot 19 engagintatabfy holding the latter in lace. Extending vertically into each topead 12 is a centralicrank shaft 20 having a washer 21 on its inner endand an operating crank 22 on its outer end there being inter osedbetween the washer 21 and the under si e of the head 12 a.

in the bottom end of the spool for ro-' helical compression spring 23that maintains the washer "21 in frictional en agementwith the topflange 24 of. the spoof 18, as clearly shown in 'Fig. 4. By turningoneof the cranks 22, the film 11 can :bewound on the adjacent spool andunwound from the other spool, thus moving the film across the printture27 which serves to support the printing 7 frame in an inclined positionlike an easel crank sha -connection with the accompanying duringtheiprinting of a picture. T In practice, theprinting frame is filled byfirst taking out the back 5 and then openin the doors 14 and swingingthe back section 0 en. The film of the two spools are then p aced in thedevice, one roller bein mounted in one pocket or casing and the otherroller in the opposite pocket or casing. In order to place the rollersor spools, .each t 20 is pulled outwardly against the tension of thespring 23 so' that the spool can be engaged over the pintle 19 and eX-.tremity of the crank shaft. After the film is thus placed in position,the back section B is locked closed as are also the doors 1 4. Theprinting aper is then applied to the film through t e opening of theframe Band the back 5 is clamped in osition. After the exposure has beenma e, the back 5 is taken out and the printing paper removed fordeveloping or washing. The film is then moved by winding on one of thespools so as to present another negative and a print of the same is madein the manner Just dee scribed. From this, .it will be seenthat theplacing of the film and its spool and the feed mg of the film for makingthe successive prints is accomplished in a simple and easy manner. v

From the foregoing description, taken in drawings, the advantages of theconstruction and of the method of o eration Will be readil apparent tothose s ed in the'art to whic t e invention appertains, and while I havedescribed the principle of operation of the invention, "together withthe apparatus which I now conslder to be the best embodiment thereof, Idesire to have it understood that the device shown is merelyillustrative, and

- that such changes may be made when des red as are within the sco e ofthe claims.

s Having thus described t I' claim'isi+' 1. In a photographic printingframe, the

e invention, whatcombination of a'main section comprising a rectangularframe open'at its center and provided with lateral extensions at the topand bottom, means for holdinga light admltting medium in the opening, .aback section hinge at its bottom to the main section and provided with acentral openin ,means for locking the sections together, 'ngedly con 1nected members removably clamped in the backsection to forma back tobear against the film, a light-excluding casing attached to corres ondinextensions, 'each casing being provi' ed a door, film-carrying spools 1nthe casings, and means for turning the spools independently.
